I can't speak specially for the nills but most that have the nills swear by it. What i can speak of is the tanaka powerhead which if you buy the power nills through cabelas and most other sites is what comes with it. You cannot go wrong. Very nice powerhead. I use the mora with mine and it rips ice like crazy. Personally I'd save the $120 from mora to nills and buy an extra auger that has chipper blades to swap out on the tanka if need be. Tanaka will mora 8in weighs about 23lbs or so. Super light. You may save like 5-7lbs is all with a drill setup by the time you add the plate, etc. Then you worry about batteries. Each setup has its pros and cons so whatever you do most, buy accordingly.
